CHEMICAL FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 322,587, dated July 21,1885.

Application filed May 14, 1885. (No model.) Patented in France July 4,1883, No. 156,402.

T all whom t may concern.-

Be it known that I, Count JosEPH AUGUSTE DE MAUCLERO, of the city ofParis, France, have invented a new and useful type of Fire- Extincteur,called The Incomparable,77 of which the following is a full, clear, andexact description.

yThe new system of extincteur77 which I have designed and which formsthe object of the present patent-application, is principallycharacterized by a novel arrangement of the acid-receiver, (of sphericalform,) an arrangement permitting the receiver to serve for an indefinitetime, and to fulfill the double object of an acid-receiver and of anadequate stopper to the apparatus.

In order that my invention may be understood, I have represented it inthe accompanying drawings, but only by way of example.

Figure l represents a vertical section through the axis of theapparatus, the spherical acidlcontainer closed and stopping thecylindrical container, being screwed upon thev latter only by two turns,which allows of the apparatus being carried without it being necessaryto be put under pressure, thedepending piece of the brass stopper onlyengaging with the stops at the third turn. This spherical containermight only rest upon the mouth of the cylinder in order to stop it. Fig.2 represents a similar section of the extincteur, the sphericalacid-container being reversed and resting upon the mouth-piece inthe'position which it-should occupy in order to be filled with acid.Lastly, Fig. 3 represents on a reduced scale the appearance of theapparatus under pressure and ready for action.

In these various figures the same letters of reference designate thesame parts.

The cylindrical container a, or body of the apparatus which contains thealkaline liquid, has the upper orifice Iitted with a collar threadedwith a female screw, b, designed to receive the male screw of theneck-piece ofl the spherical receiver overhead, and having dependingfrom its lower part two projections or stops, c, the object of whichwill be described hereinafter. This same orifice is fitted with afunnel, d, rigid with or fixed to the cap of the cylindrical receiver a.The spherical receiver e is furnished with two handles, f,

which are fixed thereto by a screw and interior nut soldered in place.At the lower part of the spherical receiver e, and surrounding theorifice thereof, is fitted the brass neckpiece g, which isscrew-threaded to it in the screw aforesaid inthe collar b of thecylindrical container. The neck-piece g is screwthreaded on the insideto receive the male screw of a stopper, h, the said screw being in acontrary sense to that of the neck-piece g.

Gutta-percha washers insure the tightness of the joints of bothcontainers. In a state of inaction the cylindrical container a, (or bodyof the apparatus) lled with alkaline liquid, is stoppered by means ofthespherical acidcontainer aforesaid, Fig. 1, and the sphericalacid-container is in turn closed by means of the lastnamed stopper 7L.In order to obtain the mixture ofthe two liquids-that is to say, toproduce instantaneous pressure-itis sufficient to turn the sphericalcontainer on the screw-thread on its neck-piece g, which engages withthe screw-thread in the collar upon the cap of the cylindricalcontainer. When the screw has sufficiently traveled, an arm, k, formedupon the stopper, is stopped by projections c, depending from the collarof the cylindrical receiver, and as the two turns of the male screw ofthe stopper h and the female screw of the neck-piece g are in contrarysense, the stopper h is unscrewed as fast as the neckpiece g is screwed.

The screw-threads are proportioned so that when the neck-piece hascompletely closed the cylinder a, the stopper of the sphere has becomecompletely unscrewed and falls into the cylinder, thus allowing theliquid acid to drop from the spherical container and mix with thealkali.

A small chain holds the stopper h in order to allow of its beingwithdrawn when the sphere is removed.

It will be understood that by this novel arrangement of extincteur thespherewill always scrve, the brass stopper being abstracted from thecylinder a after its operation by means of the chain Z.

I reserve to myself the right to so arrange the stopper of the sphereand the neck-piece that the sphere may rest upon the cylinder withoutbeing under pressure, and that the IOO simple movement of the handles fshall suffice to free the Stopper of the acid from the sphere into thecylinder a.

I claiml. In a iireextinguisher, the combination, with a Vessel forholding the alkaline liquid, of a Vessel for holding the acid, the twovessels being fitted for screw-threaded connection, and one of saidvessels having an oppositely, screw-threaded stopper, together withstops on one vessel and arms on the stopper of the other vessel, saidarms and stops being arranged for engagement to'eft'ect the removal ofsaid stopper. upon the last twin or tWo in onedirection of one vesselupon the other vessel, substantially as and for the purpose set forth.

2. In a fire-extinguisher, the vessel for holding the alkaline liquidand having a depending "collar provided also With depending stops orpendants, in combination with the vessel having a neck tted forscrewthreaded connection with the said collar, and the stopper having anopposite screw-threaded connection with said neck, and having armsadapted for engagement With the stops or pendants of said neck,substantially as-and for the purpose set forth.

3. In a nre-extinguisher, the alkaline-containing vessel having fixedaround the outside of its collar a funnel which serves as a seat to holdthe spherical acid-containing vessel superposed thereon, substantiallyas and for the purpose set forth.

The foregoing specification of new type of iireextincteur called TheInoomparable signed loy me this 27th day of April, 1885.
